Cl.202-141 3 Claims ABSTRACT OF THE DISCLOSURE A battery of coke ovenscomprises a plurality of horizontal coke ovens with hollow firingmembers on both sides of the ovens; the hollow members are connected toregenerators which in turn are connected to' longitudinal side flues atthe feed and discharge sides of the battery. The side flues empty intorespective transverse channels at the center of the battery, whichchannels lie side-byside and exhaust into a common stack.

The present invention relates to batteries of horizontal coke ovens, andmore particularly to improvements relating to smoke-exhausting flues.

The existing batteries of coke ovens compromise a plurality ofhorizontal coke ovens with firing hollow members located on both sidesthereof, said hollow members being provided with vertical channels, inwhich gaseous fuel is burnt to heat the coke ovens. The products ofcombustion or flue gases are directed through regenerators, locatedbelow the coke ovens, from the vertical channels into side flues thatare disposed on the cokepusher and coke discharge sides along the entirebattery of coke ovens. The side flues are connected to a collectingtransverse flue at the end side of the battery, said transverse fluebeing intended for directing flue gases into the stack. The crosssections of the flues are selected depending upon the maximum rate offlow combustion products, which occurs, as it is well known, at theoutlet end of the flues, and upon the minimum resistance offered to theproducts of combustion during their flow.

When constructing batteries of coke ovens composed of a large number ofhigh-capacity coke ovens, the amount of products of combustion to beexhausted increases considerably. In this case, it is necessary toconstruct smokeexhausting flues of large cross sections, which resultsin increased construction work when erecting flues and foundations of acoke-oven battery and hence in their higher cost.

At the same time, it proves to be very diflicult to maintain and controlthe draft in the flues over the length of the battery.

An object of the invention is to eliminate the abovesaid difliculties.

It is proposed to construct a battery of coke ovens provided withsmoke-exhausting flues without any considerable increase in their crosssections, said flues ensuring a steady control and maintenance of thedraft of combustion products over the entire length of the coke-ovenbattery.

The present invention envisages a horizontal battery of coke ovenscomposed of a plurality of coke ovens, each oven having on both sidesfiring hollow members provided with vertical firing channels,communicating through regenerators with lateral smoke-exhausting flueslocated along the coke discharge and coke-pusher sides of said 3,560,348Patented Feb. 2, 1971 'ice coke-oven battery and connected to acollecting smokeexhausting flue leading to the stack. In conformity withthe invention, the collecting flue is composed of two channels disposedin the middle section of the battery; one of the channels beingconnected to the side flues on the coke sides of the battery, while theother is connected to flues disposed on the coke-pusher side of thiscoke-oven battery.

An essential advantage of the present invention is that the amount ofproducts of combustion flowing through the side flues at the place oftheir junction with the collecting flue of this side is half thatobserved with the conventional arrangement of the collecting flue in theend side of the coke-oven battery. This provides for a considerabledecrease in the size of the flues and, hence, in the height offoundations, with the former rates of flow of combustion products in theflues being preserved.

The details of the present invention will become more fully apparentfrom a consideration of the following description of an exemplaryembodiment thereof, taken in conjunction with the accompanying drawings,wherein:

FIG. 1 diagrammatically represents a battery of coke ovens according tothe invention, shown in longitudinal section;

FIG. 2 is a cross-sectional view taken on line AA of FIG. 1;

FIG. 3 is a cross-sectional view taken on line B--B of FIG. 2.

The battery of coke ovens is composed of a plurality of horizontal cokeovens 1 (FIGS. 1 and 2) with hollow members 2 disposed on both sidesthereof. These hollow members 2 are provided with vertical firingchannels 4 divided by partitions 3, and the products of combustion aresupplied through oblique passages 5 into regenerators 6, saidregenerators being essentially chambers with a checkerwork of refractorybrick and located under the ovens 1 and hollow members 2. From theregenerators 6 the products of combustion are supplied through bottomflues 7 via valves (not shown in the drawing) and flue branch pipes 8into side flues 9 and 10 (FIGS. 2 and 3), located respectively along thecoke-pusher and coke discharge sides of the battery inside or outsideits foundation 11.

The side flues 9 on the coke-pusher side of the cokeoven battery emergeinto a channel 12 of the collecting flue, While the side flues 10 on thecoke discharge side of the battery emerge into a channel 13 of thecollecting flue. The channels 12 and 13, as shown in FIGS. 1 to 3, aredisposed in the middle section of the battery perpendicular to saidflues 9 and 10; and are united into a common collecting flue at thestack.

When drawing off the products of combustion from the central part of thebattery, separately on its cokepusher and coke discharge sides, theamount of products of combustion in the side flues 9 and 10 in thesection before the channels 12 and 13 will be half as that in the caseof the conventional arrangement of the collecting flue at the end sideof the battery. This fact allows, with the same rate of flow ofcombustion products, a considerable decrease in the cross section of theflues 9 and 10 and in the total height of the foundation 11 of thecoke-oven battery.

Since the length of the side flues 9 and 10 up to their transition intothe collecting channels 12 and 13 is reduced in half, favorableconditions arise for controlling the draft over the length of thecoke-oven battery by having recourse to conventional control devices.

The application of the present invention allows a reduction in the costof coke-oven batteries and improves the conditions of heating coveovens.

The invention is not limited by the embodiment thus described, and theremay be modifications thereof without departing from the concept andscope of the invention.

What is claimed is:

4 prising a foundation supporting said ovens, said hollow members, saidside fines and said regenerators, said collecting flue being in saidfoundation.
